Federal prosecutors say the arrests broke up the "Delmonico Crew," formerly led by Charles "Chuck Tourine" Delmonico who died in December of natural causes at age 81. Six alleged crew members were arrested Feb. 12, as a federal indictment was unsealed. They were Arthur Tassiello, 65, of Queens; Patrick O'Sullivan, 63, of Garrison; Joseph Belinsky, 75, of the Bronx; James Patrick Ryan, 61, of Manhattan; John Stavern, 62, of Valley Stream; and Joseph Cattaneo, 60, of Manhasset. Arthur Tassiello's brother Thomas Tassiello, 61, of Manhattan, was also charged. He was already in custody, the result of a Feb. 4 arrest of 13 suspected Genovese Crime Family members and associates.

William Donovan, also charged in the federal indictment, remains at large.

An 11-count indictment charges the group with racketeering, loansharking, interstate transportation of stolen property and illegal gambling. Thomas Tassiello was previously charged with assuming an ownership interest in a Manhattan bar after its owner failed to keep up interest payments on $100,000 worth of underworld loans.

Weiss was shot to death Sept. 11, 1989, as he climbed into his car in front of his Staten Island home. At the time, Weiss was facing the prospect of 70 years in prison for his alleged role in a mob-connected dumping racket in Arlington, NY. Prosecutors say he was killed because then-Gambino boss John J. Gotti believed he was cooperating with federal investigators. Gotti dispatched a squad of hit men to eliminate Weiss, the press release said.

D'Amico (right), 72, was already in federal custody in connection with another case. He was charged with one count of racketeering conspiracy involving murder, extortion, witness tampering, obstruction of justice and gambling and one count of murder of a witness in a federal criminal case. Sixty-seven-year-old Watts, arrested Feb. 11 in Manhattan, was charged with one count of murder of a witness in a federal criminal case.

If convicted, the men could be sentenced to life in prison. Federal prosecutors are also seeking the forfeiture of $4 million from D'Amico.

D'Amico was sentenced in Brooklyn federal court last August to serve two years in prison and pay a $4,000 fine for extorting money from a Staten Island cement plant. He was arrested a year ago, along with scores of other suspects, in a federal roundup of alleged Gambino Crime Family members and associates. Sixty-two people were arrested in the roundup. Almost all reached plea deals for short sentences. D'Amico agreed to plead guilty to the single count of extortion.
